X-Git-Tag: v0.1~27
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=15f04b24ca0b7c9bd37273a584154e2e43f14606;p=quizzer.git

cli: Add the --questions option to list questions on the stack

This lets you see what a quiz will ask without actually taking the
quiz.  In the future, it may be useful for jumping to a specific
question.
